6 Claims.

This invention relates to firearms of the double-barreled single trigger type, one of the objects being to provide a trigger mechanism which enables the user of the firearm to fire either barrel first and, by a second pull on the trigger, to fire the remaining barreLthis order of firing continuing at the will of the user and without danger of the unintentional discharge of the second barrel upon the discharge of the first.

A further object is to provide a trigger mechanism which can be used in connection with an automatic safety such as renders the gun safe while loading and unloading, it being possible to render the gun "safe after the discharge of one barrel only if desired and Without interference with the perfect functioning of the firearm or its safety mechanism.

A still further object is to provide a single trigger double-barreled gun which can be used as safely as the standard two-trigger gun. 7 Another object is to provide trigger mechanism which is of such simplicity in design as to permit manufacture of the parts readily and at low cost, all of the parts being of sturdy construction and capable of functioning properly for the life of the firearm.

A still further object is to provide a firearm utilizing selective mean located where immediate selectivity is made possible.

An object is to provide a double-barreled single trigger firearm which does not alternate in firing but continues to fire first at all times the barrel to which it has been set.

A further object is to provide a trigger which has the same length of pull for each barrel and does not shift it position after on barrel has been fired.

A still further object is to provide a trigger which is not set by recoil but is purely mechanical throughout, it being possible to set the trigger for choice of barrels either before or after firing, and also enabling the user to operate the trigger whether or not the gun is loaded.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of partswithout departing from the spirit of the invention as claimed.

- In the accompanying drawings the preferred form of th invention has been shown.

In said drawings Figure 1 i a longitudinal section through a portion of a gun equipped with the present improvements, some of the parts being shown by full and dotted lines in two different positions respectively.

Figure 2 is a section on line 2-2, Figure 1.

Figure 3 is a section on line 3-3, Figure 1.

Figure 4 is a view partly in section and partly in elevation showing the trigger, the sear lift and the recoil block, the same being set to actuate the right sear.

Figure 5 is a plan view of the parts positioned as shown in Fig. 4.

Figure 6 is a side elevation of these parts showing the sear lift and recoil block in their rear positions due to the recoil resulting from firing of the right barrel.

Figure 7 is a perspective view of the trigger and the parts carried thereby with the sear lift shifted to actuate the left sear first.

Referring to th figures by characters of reference, l designates a portion of a firearm structure having hammers 2 and 3 each of which is adapted to be held cooked by a sear. One of these sears is provided with each hammer as indicated at 4 and 5, the sears being pivotally mounted at 6' and being yieldingly held at one end in hammer-engaging position by springs l.

The sears are provided at their rear ends with laterally extended fingers B and 1 respectively which are oppositely disposed and extended toward each other.

,The trigger 8 is pivotally mounted at 9 and is held yieldingly in lowered or normal position by a spring [0 thrusting upwardly against a bracket I l. The upper surface of the trigger is flat to provide a supporting base l2 and the movement of the trigger is limited by a shoulder I3 and an extension 14, these being spaced apart a distance sufficient to permit the necessary movement of the trigger.

A transverse slot I5 extends downwardly into the trigger and has a rounded enlarged lower end I1. In this slot is slidably mounted a fiat tongue 18 having an enlargement l9 slidably seated in the enlarged portion I! of the slot. Spaced notches 20 are provided in this enlarged or rounded portion 19 of the tongue and either of these notches is adapted to receive a ball 2| against which is seated a spring 22 which, as shown particularly in Fig. 4, is held in a bore 23 by a screw plug 24. Buttons 25 are connected to and extended in opposite directions from the enlargement I9 and by means thereof the tongue I8 can be pressed laterally within the slot l5,

ball 2| serving to hold these shiftable parts in either of two extreme positions, as will be apparent.

Tongue 18 extends downwardly from and can be made integral with a post 26 which is slidable on the top or bearing surface l2 of the trigger and its extension [4, and extending through the post from front to rear at the'center thereof is a bore 27 the forward end of which is counterbored as shown at 28.

Y A recoilblock 29 is slidable on extension .54 and is connected by a bar 36 to a scar lift which is indicated generally at 3| mounted on the surface [2 of the trigger.

and is slidably Bar 30 is slidable in the bore 21 and the counterbore 28 holds a coiled spring 32 which thrusts con- 7 stantly against the sear lift 3|.

- The scar lift includes a fiat base 33 and an upstanding wing 34 integral therewith, the base and wing being connected at the center by a triangular flange 35 having an upwardly and rearwardly inclined advancing surface. A tongue 36 projects forwardly from the middle portion of the base 33.

The fingers 6 and I of the sears are extended into the path of the sear 'lift and said lift is normally located as'shown in Fig. 4 so that by pushing either one of the buttons 25, the lift 3| can be pushed to the right or to the left..

Should it be desired to fire the right barrel of the gun before the left barrel is fired, the user presses the post 26 toward the right. bring the inclined forward surface of the flange 35 into position back of the finger 6 of the right sear, and thetongue or lug 36 will be extended under the finger 6 as shown in Figure 5. Thus when the trigger 8 is pulled the finger 6 will be I caused to ride upwardly along'the inclined surface of the flange 35,thereby disengaging sear 4 from its hammer 2 before sear 5 can be disengaged. The discharge of the right-hand barrel thus produced will cause a recoil as shown in Figure 6- which will drive the sear lift 3! and block 29 backwardly against the action of-spring 32 so that there will be no possibility of accidentally lifting the left-hand sear. when the parts are returned to their normal positions by spring32 and'the trigger is again pulled, the finger I, which is normally supported at a lower level than the finger 6, as shown in Fig. 6, 'Will be. lifted by that portion of the base 33 at the left of flange 35 from the full line position shown in Fig. 1 to the'dotted line position oruntil the left-hand hammer has been tripped and the left-hand barrel has been fired.

I As long as the sear lift remains in the position to which it was first adjusted, the right-hand barrel will always be fired in advance of the lefthand barrel. However should it be desired to fire the left-hand barrel first, it becomes merely necessary to shift the block 26 to the left, thereby to bring the flange 35 into position where it will engage the finger I of sear 5 so as to actuate that sear before the base 3| can lift finger 6 of sear 4. p

v Importance is attached to the fact that the action of the recoil block serves entirely to disconnect the sear lift from the sears upon the rebound of the gun. Thus unintentional discharge of the second barrel is prevented while the trigger is being pulled to discharge the first;

barrel. Furthermore if the trigger is not entirely released, the sear lift will not go forward under the second sear and cause unintentional discharge of the second barrel.

This will.

Thereafter Obviously the trigger can be made-non-selective simply by locking the recoil post in a fixed position and eliminating the selective buttons, should that construction be preferred by the manufacturer or the user.

By shifting the safety 3'! into position above the post 26 the trigger will be held against movement.

1.-The combination with a double-barreled firearm structure including, separate hammers, of laterally spaced sears for the respective hammers, a trigger pivotally mounted in the structure, a sear lift carried by the trigger and mounted for backward sliding movement under the action of the recoil of the gun when fired, a
